Hi guys, I want to plug in arduino to an external battery. Then this battery is plugged to the current. This is the battery : http://www.amazon.it/dp/B00MMA8K58
It's that correct?
What exactly are you trying to accomplish? Power an Arduino with a smartphone battery? your question is vague...
IF and only if what I have deduced by reading your question,
You want to power an arduino uno with some sort of cell phone battery pack?
The answer is NO.
That thing says 5v. you must need at least 7v or so for the voltage regulator.
Also maybe structure your questions a bit more clearly in the future.
good luck!

The battery is always plugged to the current, but when the current stops Arduino will still have 12Ah. The question is : this is a good idea or there is better? The battery will be damaged if it is always plugged to the current?

Now my Arduino is plugged in to a usb port of computer. Isn't the voltage output 5v?
Yes, you can connect the battery to the 5V header to power the board.
If you put a low voltage diode (generally, a schottky diode) in series, it will prevent any backcharging.
You can plug in to the USB connector also to power the board. I would use a diode there as well.

What do you mean by "the current"?
